Most gold plants around the world are required by law to destroy cyanide and metal cyanide complexes in their tailings prior to discharge from the metallurgical site into the natural environment. Process leach residues are detoxified with sodium bisulphite and air (by batch), prior to discharge to leach residue ponds.

WHAT INFLUENCES PROCESS SELECTION?

There are a number of technologies available for destroying cyanide and its metal complexes, and the choice of the best method for a particular application is not simple. Complexity arises because:

• the various detoxification techniques vary widely in their ability to eliminate certain species,

• the chemical composition of the tailings from each plant is unique,

• reagent consumption and cost varies from one country and location to the next.

COST EFFECTIVENESS IS CRITICAL

The cost of treating cyanide tailings can be a significant percentage of total operating costs, and unlike other operating costs, yields no economic “return”. It is therefore very important, for both regulatory and economic reasons, to select the correct process, and then optimize the operating conditions to minimize reagent dosages. This requires a good knowledge of local regulations as well as skillful laboratory test work and piloting.

Other uses of Sodium bisulfite : It is used in waste water treatment, in the pulp and paper industry, in the photographic industry and in various other industries as a bleach or dechlorinator. It can also be used to treat flue gases to remove sulfur trioxide (SO3). Sodium bisulfite solution is sometimes used as a food additive. Sodium bisulfite solution can also be used in the manufacture of other chemicals.

Store in a cool, dry, well ventilated place and out of direct sunlight. Store away from foodstuffs. Store away from incompatible materials . Keep containers closed when not in use - check regularly for spills.
